All the organisms on your campus make up
a. An ecosystem
b. A community
c. A population
d. A taxonomic domain

Guida verificata passo dopo passo
1
Understand the definitions of each term: An ecosystem includes all living organisms in an area along with the non-living components of the environment. A community consists of all the different species living in a particular area. A population is a group of individuals of the same species living in a specific area. A taxonomic domain is a broad classification category that includes one or more kingdoms.
Identify the scope of the question: The problem asks about 'all the organisms on your campus,' which implies multiple species living together in a defined area.
Compare the definitions with the problem: Since the problem involves multiple species, it cannot be a population, which refers to a single species.
Consider the non-living components: The problem does not mention non-living components, so it is not describing an ecosystem.
Determine the best fit: The term 'community' best describes all the organisms of different species living together in a specific area, such as a campus.
